The Pennsylvania Railroad's class J28 comprised two experimental 2-6-2 "Prairie" type steam locomotives.

History

In 1905, the Pennsylvania Railroad needed a better steam locomotive, than the class E 4-4-2 "Atlantic" type. So, the railroad ordered two 2-6-2s from Alco-Schenectady. They were tested extensively and failed in railroad service. However, they were still on the roster in the early 1920s.

Specifications

The two J28s had 80 inch drivers and a 34.25 foot engine wheelbase. Engine #7453 had inboard piston valves and Stephenson valve gear, while #2761 had outside piston valves and Walschaerts valve gear. They each weighed 377,500 pounds with the tender. They had 27,504 pounds of tractive effort, had a 89 square feet (8.3 m²) of firebox space, also had a grate area of 54 square feet (5.0 m²), able to hold 7,000 gallons of water and 14 tons of coal. Despite these specifications and more, the J28 was not a powerful enough Pennsylvania Railroad locomotive and no more than the two made production.
